Research Objective

This work is part of a comprehensive time-lapse seismic monitoring program for monitoring a massive CO2 flood in a thin fractured carbonate reservoir in EnCana's Weyburn field, located in the Williston Basin, southeast Saskatchewan, Canada. There goals of this project are to:

  • develop and deploy cost-effective technology that could track the detailed changes in CO2 content as a function of time and
  • aid in the interpretation, validation, and integration of   surface seismic data (3-C and 9-C 3-D and the 3-D, 3-C and 9-C vertical seismic profile [VSP] studies) to obtain an overall understanding of monitoring technologies for CO2 .
